У вересні 1944 року, після успішного вторгнення в Нормандію, союзники готують таємну операцію «Маркет Ґарден»: зухвалий план, покликаний швидко покласти кінець Другої Світової Війни шляхом повітряного нальоту на Німеччину і знищення всіх військових заводів Рейху. Проте, поєднання невдалої бойової тактики, помилкових розвід-даних, невдачі й поганої погоди призвело до катастрофи.

September 1944. The Battle of Arnhem was one of the most audacious but ultimately controversial battles of the Second World War. Airborne drops in Holland were to secure important bridges on the route to be taken by ground forces racing to gain a foothold across the Rhine. Had it succeeded it might have ended the war by Christmas 1944.

With 2 Para isolated at the Arnhem Bridge and both 1 and 4 Para Brigades thwarted in their attempts to fight their way into Arnhem and falling back, what became the Oosterbeek Perimeter started to form around Divisional HQ at the Hartenstein Hotel. Beaten but not defeated, the remnants of 1st Airborne Division fought a grim battle with the SS supported by reinforcements and armour rushed to Oosterbeek from all over the West. Veterans and experienced battlefield guides vividly relate their experiences and take the viewer to the scene of the action. The seven days of grim and bloody fighting in the Oosterbeek Perimeter was amongst the hardest fought of all the battles in the West. It was one that the SS veterans of the Eastern Front in the Hohenstaufen Division christened the Hexenkessel or “Witches Cauldron”. All the while the the airborne soldiers were waiting for XXX Corps to arrive from the south, with the enemy pressing ever closer.

For OPERATION MARKET GARDEN to work it was vital for the Allies to secure a road to Arnhem up which vital supplies and reinforcements could move to support the beleaguered men of the Airborne Forces, especially the British 1st Airborne Division at Arnhem. This is the story of the heroic struggle waged by the men of the British XXX Corps and the US 101st Airborne Division as they struggle to open the road to Arnhem against everything the Germans could throw against the corridor. Even though the men of the Grenadier Guards manged 30 miles in 3 hrs to reach the 82nd Airborne in Nijmegen the story was not over. The men of 101st Airborne faced incredible odds as the kept the route open, it was indeed Hell's Highway.
